According to the situation of this week, heavy selling and large inventories will leading the soybean price decrease. Also, form the CME website, I get soybean bar chart, I think the recently trend is like head and shoulder pattern, therefore, I think next few weeks, the soybean price will decrease, next week I will choose short position soybean contract. In addition, I will pay my attention on soybean news in the next few days to make a final decision.
